THOMAS B. KNOWLES, OF GENEVA, OHIO.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 246,017, dated August 23, 1881.

Application filed June 18, 1881.

To all whom it may concern:

Be it known that I, THOMAS E. KNOWLES, of Geneva, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Oar-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference beinghadtotheaccompanyingdrawings,which form part of this specification.

My invention relates to caueouplers; and it consists in a hooked finger pivoted in the draw-head, and provided with an arm adapted to be operated upon by the link in the oppositedraw-head, and in parts and combination of parts, as will more fully hereinafter appear.

The object of my invention is to furnish a device by means of which cars can be readily coupled automatically, thus avoiding the dangel-s incident to the use of the ordinary coupler.

In the drawings, Figure 1 is aview in elevation ot opposing draw-heads provided with my device in an open or unlocked position. Fig. 2 is a vertical sectional view of the same, showing the couplers locked together. Fig. 3 is a view in elevation of draw-heads provided with my coupler, showing their relative position when a strain is exerted upon either car. Fig. 4 is a view in perspective of a draw-head provided with my improved coupling mechanism, showing its construction in an open position. Fig.5 is a longitudinal section, showing a modification.

In the said drawings, A represents the or dinary drawlleads attached to freight-cars.

B and B represent arms pivoted within the opposing draw-heads at b and I). These arms are provided with fingers O and O, which serve the purpose of the ordinary couplingpins, and are adapted to engage with the link carried by the opposing draw-head.

E and E are second arms, curved in form, permanently attached to the arms B and B, and turning upon the pivot b and I).

D and D are the ordinary links used in coupling cars. These are removably attached to the draw-heads A, and held in place by the pins F and F.

The operation of my device is as follows: The draw-heads A and A approaching each other, the link D strikes the arm E in the drawhead A and forces it back, thereby bringing (No model.)

the finger G down to a vertical position and through the link D, thus coupling the cars together; or, if the opposite link, D, should strike the arm E in the opposite draw-head, the arm E would be forced to a horizontal position and the finger O passed through the link D, accomplishing the same purpose as the other portion-viz., coupling the draw-heads together, as shown in Figs. 2 and 3 of the drawings.

I have described myinvention and its open ation where a link is attached to each drawhead. It is apparent, however, that butasingle link is necessary for a complete coupling of the draw-heads together. It is apparent that this draw-head is also adapted for use with the ordinary draw-head. The link of the ordinary draw-head would occupy substantiallythesamerelative position as that shown in the drawin s in eitherof the opposingdrau heads, and when the draw-heads approach each other the link should necessarilystrike the arm E or E and force the finger Oor 0 through the link, thereby coupling the cars.

In Fig. 5 is showna modification of my invention, wherein the bolt passesthrough the draw-head, instead of bearing upon the outside, as shown in the other figures of the drawings.

What I claim is- 1. In a carcoupling, the combination, with the draw-head, of the coupling-hook B O, provided with the curved arm E, and a link seeuredwithin the draw-head, substantially as set forth.

2. In a car-coupling, the combination of the hooked fingerB O, curved arm E, draw-head A,

link D, and pin F, substantially asandfor the THOMAS B. KNOWLES.
